Perps Meet Prediction Markets: Where the Two Products Converge

As of November 10, 2026, Kalshi and Polymarket run perpetual futures and Hyperliquid runs HIP-4 outcome markets beside its perps. Our view is that venues are converging on one account and margin engine, while the contracts stay separate, because a binary that jumps to 0 or 1 at resolution cannot be leveraged like a continuous price.

Our thesis is that prediction platforms and perp venues are converging on a single account, margin engine and collateral pool, while the contracts themselves stay separate products, because a binary that jumps to 0 or 1 at resolution cannot be leveraged the way a continuously priced asset can, and every major venue's rulebook already reflects that.

Who is doing what as of November 10, 2026?

In April, Finance Magnates reported Kalshi was preparing crypto perps and that Polymarket signaled its own move within hours. Seven months later, all four of the venues below sit in both products.

Kalshi moved first in the US. The CFTC approved its bitcoin perpetual, BTCPERP, on May 29, 2026, the same day it gave Coinbase Financial Markets no-action relief for digital commodity derivatives, The Block reported. By June 18, Kalshi listed perps on 11 crypto assets and, citing Bloomberg, DeFi Rate reported about $5.5 billion traded in the first two weeks. Kalshi added gold and silver perps in September and on November 5 announced single-stock perps on more than 50 NYSE and Nasdaq companies. CNBC reported leverage is capped at 4.9x and fees are waived through the end of 2026.

Polymarket went offshore. Decrypt reported that Polymarket Perps opened on September 3 and grew within hours to 67 markets, with up to 20x leverage on crypto, the S&P 500, oil, gold and silver, and 10x on single stocks. Users in the US and Canada cannot place orders. Blockhead reported the product runs on the same order book and balance sheet as Polymarket's prediction markets. At home, a Polymarket affiliate filed with the NFA on July 3 to register as a futures commission merchant, a step toward US margin trading that also needs CFTC approval, The Block reported.

Coinbase is the distribution layer. It made Kalshi-supplied prediction markets available in all 50 states on January 28, 2026, shown next to crypto, equities and cash in one interface as part of an "everything exchange" strategy, according to The Block.

Hyperliquid came from the other direction, a perp exchange adding event contracts. Its HIP-4 outcome markets went live on mainnet on May 2, 2026, per Galaxy Research, and drew around $100 million of volume in the first month, per The Block. Deployment opened to outside builders on August 29, with each deployer bonding 500,000 HYPE. Four Pillars Research counted daily HIP-4 volume of about $545,000 through most of August, rising to $2.75 million over a trailing 24 hours after the opening, with one venue, Outcome, taking 85% of it while running a $1 million rebate program.

How does a perp differ from an event contract?

Three mechanisms separate them.

Payoff. A perp's value moves continuously with an underlying asset. An event contract settles at $1 or $0. Polymarket's perps FAQ draws the line itself: its prediction markets "settle Yes or No shares at $1 or $0," while perps have "no event resolution and no $0/$1 settlement."

Resolution. A perp never resolves. It is held near the underlying by an index price built from external feeds, and a position ends only by trade or liquidation. An event contract needs an answer, and the venues answer differently. Galaxy's comparison lists UMA's optimistic oracle for Polymarket, CFTC-certified resolution sources for Kalshi, and on-chain validator votes for HIP-4.

Funding. Perps replace expiry with periodic transfers between longs and shorts. Polymarket's funding documentation samples a premium index from the order book every five seconds, averages it over a one-hour window, applies half the scale to non-crypto markets, and caps the rate at 4% per hour. Kalshi's crypto perps reset funding every eight hours, per its May 29 announcement. Event contracts need no funding because their end date does the anchoring.

Funding is also the legal fault line. CME's June 18 lawsuit against the CFTC argues perps are swaps under Dodd-Frank because of their recurring funding payments, DeFi Rate reported, and The Block quoted the complaint: "With one stroke of his pen, the Chairman overrode Congress's definition of the term 'swap'." A separate suit by the Capital Markets Alliance, whose members include Cboe and Citadel Securities, targets single-stock perps on Kalshi, Coinbase Derivatives and Bitnomial. On November 3, Judge Valerie Caproni denied a temporary restraining order but found the challengers "likely to succeed" on the claim that the CFTC lacks authority, Bitcoin Magazine reported. Ledger Insights reported the first four Kalshi stock perps traded about $23 million in 24 hours; Kalshi's own announcement said users traded over $300 million on launch morning. Both cases are pending.

Why is leverage on a probability the hard part?

Perp margin assumes prices move in steps small enough for a liquidation engine to act. Polymarket sets maintenance margin at 0.5 divided by maximum leverage, which is 2.5% on a 20x market, according to its margin documentation. A binary priced at 90 cents can go to zero at resolution, a total loss in one step, with no intermediate price for a liquidator to hit.

The venues' designs show they know this. HIP-4 outcome contracts are fully collateralized with no leverage and no liquidations, and Galaxy states the principle as "Maximum loss is always your entry cost." Four Pillars noted that binaries are awkward inside a margin engine because they jump from 0 to 1 at a threshold, and that Hyperliquid's documentation is inconsistent on whether outcome positions net against perps.

Kalshi's attempt to add leverage is built around the same problem. The proposal filed by its clearinghouse, Kalshi Klear, on September 22, as reported by PYMNTS, would raise capital requirements as a contract approaches expiration, limit access to self-clearing members that meet capital thresholds, and exclude sports, culture and mention markets. Polymarket's perps API has carried reserved endpoints for "odds orders" since at least October 22, but its changelog entry for November 10 still lists placement as disabled in production.

Our read is that leverage on probabilities will arrive in a narrow form. Kalshi's design returns toward full collateral as resolution nears, so the leverage applies to the path of the probability while the outcome itself stays funded. That fits a fund trading a long-dated macro contract. It fits a retail bettor on a weekend game poorly, and Kalshi has left sports out, whether for that reason or for regulatory comfort we cannot tell.

Where does this converge?

Galaxy's Will Owens wrote in June that "Every major venue is moving toward the same 'trade everything from one account' model from a different starting point." We agree with the destination, with one qualification: what merges is the account, the collateral and the margin engine, and the contract types stay distinct inside it.

The economic case for one account is hedging. Four Pillars describes a Hyperliquid trader offsetting a perp with a binary that settles on the same mark price, with no basis risk. Kalshi CEO Tarek Mansour framed the relationship in the May announcement: "If a prediction market is a photograph of what the world thinks right now, a perpetual is a film."

The usage data says the combination is early. Four Pillars estimated that HIP-4 outcome markets trade about 3 basis points of the perp volume running through the same accounts, against roughly $7.7 billion of daily Hyperliquid volume. Blockhead described volume on Polymarket's largest perp contracts after launch as low single-digit millions of dollars. Headline perp volume also needs care: CNBC found Kalshi's bitcoin and ether perps traded about 42 and 66 times their open interest, against about one third for Hyperliquid's ether perp, and cited a Wall Street Journal report that the CFTC was examining the ether trades. Kalshi denies wash trading and attributes the flagged activity to arbitrage.

What is the strongest case against our view?

The strongest objection is that the products will merge after all. A venue could list a perpetual on a probability itself: a contract that tracks a market's implied odds, pays funding and never settles. That would make leverage workable, because the contract never jumps to 0 or 1. Polymarket's disabled odds orders might be a step in that direction.

We take this seriously. As of November 10, 2026, none of the four venues lists such a contract, and we do not know what Polymarket's odds orders will do, so we cannot count them. A probability perp would also need an index, and for most events the only available index is a prediction market's own price, which in thin markets is often set by a handful of wallets. Until that index is deep, a probability perp is leverage on a thin order book.

The second objection is legal. If Judge Caproni's preliminary view holds, or CME wins, US perps could be pushed toward SEC or swap rules. That would change who can offer the perp leg to Americans and slow the US version of the one-account model. It would leave the mechanism argument intact, and the offshore venues would carry on.

What would change our mind

• A major venue listing a perpetual whose index is an event probability, with open interest above $100 million.
• The CFTC approving Kalshi Klear's event-contract margin with requirements that stay flat into expiry.
• Polymarket enabling odds orders in a form that carries leverage through resolution.
• A final court ruling that perps are swaps, followed by Kalshi or Coinbase withdrawing US perps.
